GRATE ATTACHIVI ENT.

SPECIFICATION forming part of Letters Patent No. 464,930, dated December8, 1891.

Application filed June 16, 1891. Serial No. 396,490. (No model.)

To all whom, it may concern:

Be itknown that I, GEORGE WV. DAVIS, a citizen of the United States, anda resident of Memphis, in the county of Shelby and State of Tennessee,have made new and useful Improvements in Grate Attachments; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichitappertains to make and. use the same,

- reference being had to the accompanying drawings, and to letters ofreference marked having more particular reference to the pro-- ductionof a device for heating and cooking articles and adjusting a blowerwhereby the odor of the article being cooked may be caused to ascend thechimney, the details of all of which are shown in the accompanyingdrawings, and will be hereinafter fully described.

In the drawings, Figure 1 is a front perspective elevation of a gratewith attachment in place. Figs. 2 and 3 are respectively a plan andfront edge view of the shelf in the form applied to a grate having anoval front. Figs. at and 5 are respectively a plan and edge view of thetrivet. Figs. 6 and 7 are a side and edge view, respectively, of thedentated standard. Figs. 8 and 9 show, respectively, a plan and edgeview of the curved bracketarm having elongated or key-seated hole forpassing over the standard shown in Figs. 6 and 7. Figs. 10, 11, and 12are views of the central pendent bracket, being in the order mentioned aback, an edge, and a lower end view thereof. Figs. 13, 14:, and 15 arerespectively front, edge, and lower end views of the end supportingpendent brackets. Figs. 16 and 17 show elongated head-securin g bolts.Figs. 18 and 19 show, respectively, a plan and an edge view of theperforated top dog. Figs. 20 and 21 are views of the centersecuringbolt. Fig. 22 is a detail in front elevation of the blower,showing the lips which rest on the arms shown in Figs. 8 and 9.

The shelf a, preferably of cast metal, is made of the desired size andconforms at the back edge to the horizontal contour of the grate-basket,the front edge being of any de-.

sired form, and may, if desired, be of fanciful shape or design, ahandle a being provided for handling the shelf. A flange a is formedprojecting downwardly from the under side of said shelf and extendingalong the front edge and back along the end edges, near as possible tothe grate-basket, said flange being for the purpose of preventing anyashes raised in the stirring of the fire from passing upwardly andgathering upon the draperies or in the cooking utensils. This shelf aisremovably secured in place in the desired position across thegrate-basket by a set of brackets, 1) representing the center one, (bestshown in Figs. 10, 11, and 12,) and b beingthe end ones, which differslightly in detail from said center brackets 12, both, however, havinglips 12 and b projecting in opposite directions from the bottom end ofeach bracket, the lips 17 of the end brackets pressing on and projectingpartly across the under side of the shelf a, the neck 11 entering one ofthe notches cf, Fig. 2, and the lips 13 of the central bracket pressingon the upper side of the said shelf a, the neck 19 entering the notch ain said shelf. The lip on each of the brackets project under the properone of the grate-bars and from the stationary jaw of a clamp, as will bepresently seen. The upper ends of the brackets are reduced andscrew-threaded, and upon this reduced portion of each of said bracketsfits the part d, (best shown in Figs. 18 and 19,) the lips d thereonprojecting back of the grate-bar and forming a grapple, and the fly-nutd is secured on above said part 61, and by tightening same thegrate-bars are secu rely clamped and the brackets held in place. Thehole (i may be elongated, as shown in Fig. 18, to allow adjustment fordifferent widths of grate-bars. The part (I is provided with apertures dfor the curved armse' of the trivet e, which is made reversible by meansof a bifurcated curved arm vertically disposed on the edge thereof. Thebrackets 12 and b are provided with slots b the bolt f (shown in Figs.20 and 21) passing through the slots in the bracket 1) and booking overthe grate-bar and tending to resist the up ward motion of said bracket,and hence pressing the lip b against the shelf a. The end brackets b areheld in place by bar-headed bolts f, (shown in Figs. 16 and 17,) one ofwhich presses through the slot in each bracket and catches back of twograte-bars. Set

in one of the holes (1 of each of the two end pieces cl is a standard g,which has one edge dent-ated, and over each of these standards slips anarm g by reason of a hole 9 therein having a notch 9 which if turnedinto juxtaposition with the said teeth will slip over them;lout ifturned away from them the arm remains seated in one of the interdentalspaces, in which it may be turned in a horizontal plane. This arm may beroughened or dentated on its upper surface, if desired, to prevent theslipping off of the blower h. Said blower has lips h, which are providedin case the blower is not wide enough to reach said arms, the objectbeing to allow the said arms to be placed at one side out of the waywithout the necessity of enlarging said blower. Thus it will be seenthat the said blower may be lowering or elevating, the said arms 9 beingadjusted to direct the draft so as to promote combustion to the desiredeXtent'or simply carry the odors resultant from cooking up the chimney.I

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

1. In a device of the class specified, the standards secured to thegrate and arms vertically adjustable thereon and a blower adapted to beseated upon said adjustable arms, for the purpose specified.

2. In a device of the class specified, the two standards carrying thearms for supporting the blower, and the blower it having lips h thereonadapted to rest on said arms, substantially as specified.

3. In a device of the class specified, the plate d, secured to the grateand having an aperture therein, in combination with the trivet e, havingcurved arm 6, for the purpose specified.

4. In a device of the class specified,ashelf having a notch in its backedge and a bracket clamped to the grate-basket, said bracket having aforwardly-projecting lug adapted to rest under the said shelf and a neckadapted to enter the notch in said shelf and prevent the uprising of theback edge thereof, substantially as and for the purpose set forth.

5. In a device of the class specified, the shelf a, supported bybrackets clamped to the grate-basket and extending under said shelf, andanother bracket also clamped to said grate-basket and bearing on the topof said shelf.

In testimony whereof I hereunto ,affix my signature in presence of twowitnesses.
